To all whom-it may concern.-

Be it known that I, ALEXANDER LECLAIR, a subject of the King of Great Britain, residing at 195 Delinel street, in the city and district of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Gaining-Machines, of which the following is a specification.

This invention relates to improvements in The invention consists, essentially, of a plurality of standards, shafts j ournaled therein, adjustable pedestals arranged in proximity thereto, rotating knives mounted on said shafts and pedestals, a carriage traveling over said standards, clamping mechanism attached to said carriage, and a replaceable table rest-- ing in said carriage.

The ob ects of the invention are to slmultaneously make a number of cuts in such articles as belt-rails used in car construction and without changing the position of said belt-rail in the carriage or said machine tofinish the number of cuts necessary, and thus complete the full number required and turn gear through A B in Fig. 6.

the rear thereof.

out said belt-rail ready for use and to provide in such'a machine a facility in operation and absolutely secure means of retaining said belt-rail in position during the operation of cutting.

In the drawings, Figure 1 is a general perspective view of the machine. Fig. 2 is a plan view of a portion of the machine from above. Fig. 3 is an elevation of the machine from one end. Fig. 4is a side elevation showing a detail of the clamping mechanism. Fig.

'5 is an end view of the clamping mechanism shown in Fig. 4. Fig. 6 is a detail of the runhing-gear, showing the locking mechanism. Fig. 7 is a cross-sectional view of the running- Fig. 8 is a vertical section of a pedestal. Fig. 9 is a perspective detail of a knife. Fig. 10 is a perspective detail of a knife-blade.

Like characters of reference indicate corresponding parts in each figure.

Referring to the drawings, a represents the standards having the upward extensionsb at c is a tie-rod extending through the upper ends of said rear portions 1) of the standards and secured on the upper side of each end portion by the set-screws d.

e is a tie-rod extending through the standards at f and securely bolted on the outer side of each end standard, and 9 represents tubes encircling said rod e'between said standards and spacing the same one from the other.

It is a shaft journaled in the bearings i in the standards'and having at one end thereof the pulley j, which is suitably connected with the driving mechanism by the belt 76.

Z is a knife having an elongated body portion we and mounted on the shaft h and rotating therewith. 'n, is a set-screw inserted in a correspondingly-threaded orifice in said body portion m and having its inner end abutting the said shaft h.

0 represents knife-blades secured on the flattened ends 29 of the body portion m by the bolts 9. The blades 0 have a chisel edge 1" and flanges s exte'ndin up each side at right angles to the flat o' the blade 0, said flanges at their outer ends having the chisel edges t, terminating in the projecting sharp points u,-so that the said edges t of the flanges are the first portion of the knife to engage the material to be cut, thus starting an incision in the material on each side of the cut to be made, which is readily followed up by the edge '7". The inwardly-projecting flanges, which are upwardly projecting in the operation of cutting, form the'means of making a perfectly clean cut from the edges.

1) represents hoods supported on the tubes 9, which pass therethrough, and further supported by the arm w, secured on the rod 0, which passes through the upward extensions 1) at y and to the top of the said hoods. The hoods 1) each shield one of the knives Z.

z is a bed-plate extending along-the full length of the machine at the front thereof and firmly secured to the flooring-by the bolts 2. 3 is a guideway formed longitudinally'at each side on top ofthe plate. a

4. represents corrugations formed in the center of the bed-plate .2 and are designed to serve as cleats.

5 represents pedestals traveling on the bedplate 2 and held thereto by the bolts 6, projecting through the narrow or neck opening 7 from the guideway 3 and through thebase of the pedestals, being locked thereto by the nuts 8. The pedestals 5 are hollow and have the bearings 9 extending through the sides thereof and the openings 10 at the front thereof. 11 is a turret mounted onthe top of each of said pedestals, and 12 represents bolts extending from the narrowed neck portion 13 of the slot 14 in the turret 11 through the upper face of the pedestal into the recesses 15 and securely fastened by the nuts 16. The turrets 11 have the extending portions 17 and 18 and the track 19 extending continuously therealong through said turret and extending portions.

20 is a crown traveling on the track 19 and haying the bearings 21 formed at its inner en s.

22 is a rack formed longitudinally on the inside of the crown 20. and projecting into the-grooved portion 23 of the turret 11.

24, is an upright shaft, supported ina suitable bearing the turret 1 1 and having a geare l me ng i h th ra 22.

26; is a miter-wheel at the lower end of the shaft 24.

27 is a shaft extending from end to-end of the machine through the bearings 9 in the sides, of the pedestals 5 and broken at 28 and coupqlled and having the miter-wheels 29 mes 'ng with the miter-Wheels 26, conseuently communicating the motion of the shaft to the racks 22, thus operating the crowns 20- forwardly or backwardly.

30 represents hand-wheels fixedly secured to the outer ends of the shafts 31 and having mounted thereon at the inner ends. thereof the miter-wheels 32, coactingwith the miterwheels 33. The turning of either of the hand-wheels 30 will rotate the shaft 27, which will in turn operate the miter-wheels 29 coacting with the miter-wheels 26, thus rotating the shafts. 24 and through the gear connection with the racks 22 move the crowns 20 backward orforward. The coupling of the shaft 27 at 28 will enable the hand-wheels to be operated independently of each other, and consequently the portion of the shaft to which each is connected.

34 represents rotating knives formed similarly to the knives Z and secured to the shaft 35, which are journaled in the bearings 21. 36 represents convex pulleys, fixedly secured to said shafts and connected by the belts .37 to the driving mechanism. It will be thus seen that there are the rotating knives Z, which must be approached with the material to be operated upon in order to make use of their cutting edges, and the knives 34, which must be advanced to the material to beoperated upon in order to secure the use of their cutting edges. Again, itwill be noticed that the knives. 34 may be fixed at any angle t Which it is desired to make a cut in the'said material by setting the turrets 11, while the knives at the rear of the machine form the means of making the straight cuts across.-

38 is, the runningear of the carriage, formed of the inverte U.-shaped blocks 39, inside of which are journaled the rollers 40,

travel on the prepared tracks 41 on the standards. 42 is a shaft. j ournaled in the blocks 39 and extending from one end of the machine to the other and carried by said running-gear in its movements and projecting slightly beyond the said blocks at each end of the mac) ine having the keyway 43 in said projecting ends. 44 is a rod extending the full length of the machine and through the said blocks 39, having the nut-fastenings 45 at each end thereof. 46 represents sections of tubes encircling the rod 44 between the standards and forming a means of spacing the parts just above said standards and with the iod 44 generally bracing and tying th mach ne. 47 s a han -Whe l at he n of the shaft 48, which is journaled in a bracket 49, secured to thebed-plate and the floor and also journaled at its inner end in the frame of the machine at 50. 51 is a miter-wheel mounted at the end of the shaft 52 is a shaf eXtending the full length of the machine and journaled in the bearings 53, supported by the standards, and having mounted thereon the miter-wheel 54, meshing with the miter-wheel 51, and the ear-Wheels 56, meshing with the racks 57 ormingpart with'the blocks 39, thus providing the means of moving the said runninggear of the carriage forwardly and rearwardly on the standards of the machine. 58 represents brackets having the supporting table portion 59v and the split lower extension 60 and the bearing 61, through which passes the shaft 42, the split portion 60 being securely clamped to said tubes 46. 62 is. an angle-iron having a base-section 63 thereof bolted to the table portion 59 and an upwardly-extending section 64 and the section 65 extending over the table portion from said upward section 64 and formed to spread over the material to be cut. 66 is a dovetail groove or guideway formed on the said brackets 58 adjacent to the table portion 59. 67 is a shoe having its tailpiece 68 correspondingly formed to the dovetail groove 66 and sliding therein. 69 is a rack orming part with said tailpiece. The shoe 67 is provided withrecesses 7 Ofrom the inner surface of the upwardly-projecting portion 71, said recesses terminating in the orifices 72. The spiral springs 73 are introducedin said recesses.

74 is an angle-iron clamp formed'to, spread over thematerial to be cut and having an angular formation following the line of the cut to be made and having the bolt-holes 75.

76 is a bufier introduced between the inner surface of the shoe 67 and the outer surface of the angle-iron clamp 74.

77 represents bolts extending through the orifices 72, the spiral s rin s 73, and thecorrespondinglythreaded ori ces. 78 in the buffers, 76. into the bolt-holes in the angleiron 74. The springs 73 continually press on the buffers 7 6, which in turn are pressing on the clamps 74, thus forming a means of equalizing thepressure on the clamp and accommodating an uneven surface in the material.

79 is a removable table resting on the table portions 59 of the brackets 58 and extending for the full length of the machine. table may be of any desired thickness, or if This necessary an additional board may be added thereontop, and in this connection it may be here pointed out that this simple means of adjustability in regard to thickness of the table is a very salient feature in the invention and not known, as far as I am aware,

in this class of machine, for it does away with all forms of complicated mechanism for raising and lowering that portion of the machine or the knives.

80 is the belt-rail, which is here shown as the material to be operated upon.

81 represents segmental gears mounted on the shaft 42 immediately beneath the rack 69 and meshing with said rack and secured to said shaft with the set-screws 82.

83 represents levers secured on the projecting ends of the shaft 42 and keyed thereto at43.

It will be seen that on throwing the levers over one way or the other the tailpiece 68 is drawn backwardly or forwardly, as the case may be, and consequently alter the position the weighted portion 86, which is sufficient to keep the point 87 of the said pawl from engagement with the ratchet-wheel 85. Thus the clamping mechanism is freely turned inwardly or outwardly. The pawl when placed in engagement with the ratchet-wheel holds the clamp 74 in position. In order to provide a locking device, a small dog 88 is dropped over atthe point 89 on the blocks 39. This dog 88 may be thrown over at any time it is desired to lock the pawl in engagement with the ratchet-wheel and retain the pressure of the clamping mechanism on the belt-rail.

Having described the various parts in detail, I shall now more particularly explain the operation thereof. The ulleys and 36 are set in motion, rotating t e knives Z and 34. The belt-rail to beoperated upon is then laid on the table 60, extending probably the full length of the machine. The knives Z are adjusted on the shaft h to a position opposite eachof the places at which the cutsare to be made in the belt-rail. This is accomplished by merely loosening the set-screw fastening the said knives to the shaft and slipping said knives along. The knives 34, journaled in *the crown of the turrets on the pedestals 5,

are set at the proper angle at which the cut is to be made in the belt-rail by loosening the set-screws l2 and turning the turret on said pedestals until the blade of the knife points in the direction in which it is intended to make the cut in the rail. The set-screws 12 arethen tightened up, firmly securing said turret in proper position. The pedestals are then pried along the" bed-plate 2 by inserting the oint of a lever under the base of the pedesta s and against one of the corrugations or cleats 4. Each pedestal is thus moved to the position where it is desired to make the cut in the belt-rail. One or both if the shaft 27is uncoupled of the hand-wheels 30 are then turned, rotating the shafts 31, which in turn ouslyrotating, intocontactwith thebelt-rail to make the necessary cuts therethrough. The shape of the knives is a very important feature in this invention, as the upturned flange at each side of the knife insures a clean cut on each side of the slot made in the belt-rail. A

The splintering of the belt-rail is prevented by the angle-iron 74 extending angularly alongside the part of the belt-rail in which the slot is to be made. When the knives have made the cut necessary in slotting the belt-rail, they are drawn back by again turning the hand-whee1s 30, and the belt-rail is then ready for the straight cuts to be made by the knives Z. The hand-wheel 41 then turned. This turns the miter-wheel 54, which rotates the shaft 52, and mounted on the said shaft are the gear-wheels 56, meshing with the racks 57 on the blocks39. The carriage is thus propelled toward the knives Z, for as the said gearwheels rotate the runninggear 40 of the carriage travels inwardly on the prepared tracks 57 and carries the beltrail under the knives l, which make the necessary slots therein and com lete the 1nanufacture of said belt-rail. T e circular saws 90 are provided at each end of the shaft h and saw off any extra length on the ends of the make t 1e operation of the machine successful.
